GRAIN WEIGHER AND REGISTER.

SPECIFICATION forming part of Letters Patent No, 342,600, dated May 25,1886.

Application filed February 5, 1886. Serial No. 190.924.

T0 aZZ whom, it may concern.-

Be it known that I, JACOB I-LUVK, a citizen of the United States, and aresident of Canton, county of Stark, and State of Ohio, have in vented a new and useful Improvement in Grain Metersand Tallies, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in automaticgrain meters and tallies; and it consists in providing means by which thrashed grain may be weighed or measured and tallied.

My invention also relates to the detail and combination of parts, as described,and set forth in the claims.

Similar letters of reference indicate corresponding parts in all the figures of the drawings hereunto attached.

Figure 1 is a view showing the meter as used in connection with a thrashing-machine. Fig. 2 is a view in isometric of meter detached. Fig. 3 is an isomctrical view of vibrating valve and rock-shaft with crank and register-actuating pawl. Fig. l is a view in isometric showing interior of the hopper, location of vibrating valve, and enlarged view of parts.

Letter A represents an elevator-trunk which iucloses the elevator, which may be of any ordinary kind, with strap and bucket operated by rollers at the bottom and top of the trunk, but not shown in thedrawings. Grain may be raised and thrown into thehopper B or be conveyed to the hopper through a spout. The hopper B is preferably made of wood, the upper section, from (r to ."r, twenty-four inches long and four inches deep and eight inches wide. Thelowersection is divided and formed into two prongs or spouts, O and D, that diverge from the point of connection with the hopper, and by which grain may be conducted from the hopper into the bag E or other receptacle. On a line from z to z,and aboutthe center of the hopper B. the boards a a are joined, and on the ends of these boards rests the shaft 1?,one of the ends, 0. penetrating and restingin a perforation provided foritin the back board, (I, of the hopper, the other end projecting through an aperture, 0. provided for it in the front board of thehopper. This front end of the shaft F is provided with a crank, g,and which maybe integral with the shaft. There is also (No model.)

provided a projecting finger, h, to which is pivoted the pawl To the body of this shaft is attached, by the straps f f, a vibrating board or valve, G, which may be vibrated from one side of the hopper to the other, as shown by the dotted lines from 3 t0 3 by the rocking of the shaft in its bearings e. A steelyard or scale-beam, H, is pivotally connected to and supported by a bracket. J,which may be con nected to the side of a thrashing-machine, or elsewhere, as occasion may require. The outer or free end is passed through the loop k. From theotherend ofthebeamHissuspendedaswinging platform supporting bar, K, to the lower end ofwhich is connected a platform, L, as sup port for bags or other grain-receptacle. The crossbar in may be supported by a connection with the spoutsO and D, as shown in Fig. 4, and the swinging bracen has a pivotal connection with the bar in, as shown in Figs. 2 and S. The lower end of the brace a has a pivotal connection with the swingingplatformsupport K, as shown at 0, Fig. 4. The bar K is provided with a slot, 1), into which is in serted the end r of the crank g. On the face of the hopper B there may be placed any of the well-known and approved tallies adapted to be actuated bya reciprocatingspring-pawl. The mouth of the bag E may be supported by hooks on the end of the spouts or otherwise, as may be preferred. The movable weight 8 may be of any of the well-known and approved beam-weights adapted for such use.

The operation is as follows, taking the parts as now shown by the drawings: The valve G resting against theside of the hopper and over the opening into the spout O, place a bag on platform L, with mouth secured about the lower end of the spout D, set the weights at the figure on the beam H, indicating the amount required in the bag-saytwo hundred pounds. when that amountof grain has passed into the bag, the long end of the beam will be raised, and the platform and rod are caused by the brace n to swing over to the other side and bring the centerot' gravity of the platform and the weight of the grain on one side there of to the lowest point. This center of gravity is therefore at a certain point beyond the position where the brace-rod is vertical,and consequently causes the platform to swing back and forth each timeabag isfilled. This movement of the bar K just described moves the crank g, rocking the shaftF so as to throw the upper end of the valve G over the opposite side of the hopper, changing the current of grain from the spout D to the spout C. An empty bag having been placed on the empty end of theplatform, and the openend attached to the spout G, the filled bag may be removed. The beam H will drop to the bottom of the loop k, thereby raising the bar K and the lower end of the brace n above the lowest point, b,of the circle described by it as itis vibrated (see dotted lines, Fig. 4) by the bar K, and in which position it will prevent thebar K from swinging until the grain resting on the platform L overbalances the long end of the scale-beam. Otherreceptacles maybe used in place of bags when desired. By the movement of the shaft F, as hereinbefore mentioned, the finger h,with ratchet-pawl i, one end of which engages with a ratchet-wheel, t, will be vibrated.and by this movement rotate the registering-dial u. The pawl is held in engagement with the rackwheel if by a spring, 1). When desired, the gearing of the register may be adapted for the use of tWoactuating-pawlsandratchet-wheels,so that the movement of the platform-supporting bar in either direction will actuate the register.

Having thus fully described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an automatic grain-meter, the combination of the hopper B, having two outletspouts, O and D, the vibrating valve G, shaft F, as described,the platform-supporting bar K, the brace 'n, as described, and the scalebeam and movable weight, substantially as described, and for the purpose set forth.

2. In an automatic. grain-meter, the combination of the hopper B, the vibrating valve G, theshaft F, having a crank-section, g, the platform-supporting bar K, platform L, the brace 12, and the scale-beam and weight, substantially as described, and for the purpose set forth.

3. In an automatic grain-meter, the combination,with the hopper, two outlet-spouts, the vibrating valve, the crankshaft, and the pawl secured to said shaft, of the scale-beam, a registeringdial, a bar suspended from the scalebeam and connected to the crank-shaft, the platform secured to said bar, and the brace n, substantially as set forth.

In testimony whereof I have hereunto set myhand this 28th dayol" January, A. D. 1886.

JACOB HAWVK.
